Configuring refresh rate for IPv6 NetStream version 9

templates

Version 9 is template-based, so the NetStream device needs to resend the new template to the NetStream

server for an update. If the version 9 format is changed on the NetStream device and not updated on the

NetStream server, the server is unable to associate the received statistics with its proper fields. To avoid
such situation, configure the refresh frequency and rate for version 9 templates so that the NetStream

server can refresh the templates on time.
Follow these steps to configure the refresh rate for IPv6 NetStream version 9 templates:
